BACKGROUND OF THE INVENTION 1. Technical Field

The present invention relates to the field of fishing gear, inparticular to a foldable dip net provided with a handle and particularlysuitable for fly fishing and a method for using the foldable dip netprovided with the handle.

2. Description of Related Art

Fly fishing is usually adopted by senior fishing enthusiasts to catchsmall predacious fish from lakes, reservoirs, rivers or brooks at theend of the spring and the beginning of the summer (from March to April)every year when winged zooplankton becomes adults by means of thecharacteristic that the predacious fish catch food intuitively and donot determine whether or not the food is swallowable until placing thefood in the mouth. Fly fishing creates a false impression that wingedinsects such as flies, mosquitoes, dragonflies, butterflies and mothsfall into water with bionic bait (artificial bait) to stimulatepredacious fish such as hemiculter leucisculus, cutter alburnus andred-tail xenocypris to catch.

When fly fishing is used for catching fish, hooked fish should bescooped in time so as to be prevented from escaping. There are typicallytwo types of dip nets at present: fishing dip net rod disclosed byChinese Patent Application No. 201721784054.7 and an internal triangularfoldable dip net disclosed by Chinese Patient Application No.201420376912.4, the dip nets in both patents are composed of a dip netrod and a net rack, and the dip net rod in the prior art is a straightrod.

As for fly fishing completed in air, if the straight dip net rod isadopted, it will be very difficult for the fishing enthusiasts to scoopfish by holding the fish net rod due to the large force; the angle ofthe straight dip net rod is difficult to control in the fish scoopingprocess, and consequentially, the fishing enthusiasts may miss theoptimal fish scooping opportunity and hooked fish escape again.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

For a better understanding of the present invention, the presentinvention is expounded below with reference to embodiments. Thefollowing embodiments are used to explain the present invention, but arenot intended to limit the scope of the present invention.

For the sake of a brief description of this application, the applicantomits ‘string bag’ in the following text description, and the string bagis not shown in the figures either. But those skilled in this fieldwould appreciate that the string bag should be attached to or mounted onthe net rack when the foldable dip net in this patent application isused.

As shown in FIGS. 1-3, a foldable dip net provided with a handlecomprises a handle 1, a connector 2 and a net rack 3. The handlecomprises a U-shaped support 11. A handle lever 12 is arranged at thefront end of the U-shaped support 11 and has two ends separately fixedto inner walls of rod pieces on two sides of the U-shaped support 11. Anarm rest plate 13 is arranged at the tail end of the U-shaped support 11and is of an arc-shaped structure with the middle concave downwards. Ahanging plate 14 is arranged behind the arm rest plate 13 and isprovided with a through hole 15 allowing a sling to penetrate through.The sling and a hook (not shown) are tied at the through hole. When notused, the foldable dip net provided with the handle can be hung onfishing wear through the hook and the sling.

As shown in FIG. 1 and FIG. 4, the connector 2 comprises a mounting basebody 21 fixed to the forefront the U-shaped support 11. A cavity isformed in the mounting base body 21. A plurality of rotary pin bearingseats 29 are arranged in the cavity side by side at intervals.Semicircular holes matched with a rotary pin are formed in the rotarypin bearing seats 29. A rotary pin 31 at the end of the net rack 3 ismounted in the semicircular holes in the rotary pin bearing seats 29. Amounting hole is formed in the upper surface of the mounting base body21. A lock structure 22 is arranged at the mounting hole. The lockstructure 22 comprises a buckle plate 26 hinged to the mounting basebody 21 through a rotary shaft 28. The lock structure 22 is providedwith a reset spring 264 and a bolt 265. The reset spring 264 and thebolt 265 are separately located at the rear end 262 and the front end261 of the buckle plate 26. The tail end of the net rack 3 is hinged tothe mounting base body 21 through the rotary pin 31. A clamping groove32 is formed in the side wall 311 of the rotary pin 31 and is matchedwith the bolt 265 at the front end 261 of the buckle plate 26.

When the net rack 3 is completely unfolded, the lock structure 22rotates into the clamping groove 32. When the net rack 3 is folded, thelock structure 22 is not buckled in the clamping groove 32. When thefoldable dip net is used, the net rack 3 is pulled to rotate the rotarypin 31, and the clamping groove 32 rotates towards the buckle plate 26;when the clamping groove 32 overlaps with the bolt 265 of the buckleplate 26 in position, the reset spring 264 bounces upwards, the buckleplate 26 is buckled in the clamping groove 32, the net rack 3 cannotmove anymore, and fish can be scooped. On the contrary, when thefoldable dip net provided with the handle needs to be folded, the end,away from the net rack 3, of the buckle plate 26 is pressed by hand tocounteract the acting force from the reset spring, then the end, clampedin the clamping groove 32, of the buckle plate 26 tilts, the rotary pin31 is released by the lock structure 22, and then the net rack 3 can bepulled to be folded.

As shown in FIG. 1, FIG. 3 and FIG. 4, the connector 2 is of an airtightwaterproof structure. A light-emitting unit is arranged in a cavity ofthe connector 2 and comprises a battery, a control switch 23, a controlchip and an LED lamp 24. The LED lamp 24 is fixedly mounted at the frontend of the mounting base body 21. The control switch 23 is arranged onthe upper surface of the mounting base body 21. A battery case 25 isarranged in the mounting base body 21. A battery case cover plate 27 isarranged on the back of the battery case 25. The battery case coverplate 27 is screwed on the battery box 25 with screws. When the batteryneeds to be replaced with a new one, the battery case cover plate 27 isdetached from the battery case 25 by unscrewing the screws. The batteryand the control chip are both mounted in the battery case 25. Thebattery, the control switch 23, the control chip and the LED lamp 24 aresequentially connected through a wire. The battery is a 9V instrumentbattery and is able to continuously supply voltage-reduced power to theLED lamp 24 for 120 hours. The control chip is an EN8F202 LED-drivesingle-chip microcomputer chip and is able to control the LED lamp toemit different lights. For instance, if the control switch 23 is pressedonce, the LED lamp emits a near light; if the control switch 23 ispressed twice, the LED lamp emits a distant light; if the control switch23 is pressed three times, the LED lamp emits a scattered light; if thecontrol switch 23 is pressed four times, the LED lamp emits acontinuously-twinkling light; and if the control switch 23 is pressedfive times, the LED lamp is turned off. The LED lamp can also be setthrough the control chip to be automatically turned off under thecondition where the control switch 23 is not pressed within 5-10minutes.

A method for using the foldable dip net provided with the handlecomprises the following steps: the net rack 3 is locked by the lockstructure 22 after being unfolded, and a user holds the handle lever 12from below with the palm facing upwards and the back of the arm leaningagainst the upper surface of the arm rest plate 13 and then shakes theforearm to apply an acting force to the dip net to scoop fish. Accordingto the lever principle, fish can be scooped more effortlessly byapplying the acting force to the net rack under the combined effect ofthe wrist and the arm, and the fish scooping angle can be controlledmore easily, and fish can be scooped more accurately; because the armrest plate 13 is matched with the contour of the arm, the contact areabetween the arm and the arm rest plate 13 is enlarged, the user feelsmore comfortable and is protected against arm pains. When fishing atnight, the user can cooperatively use the light-emitting unit to clearlysee the condition under water and to attract fish.
